五星大酒店空调通风系统设计+CAD图纸(2)
根据《高层民用建筑设计防火规范》的规定，在本设计中，在以下符合规定的房间设置防排烟：地下1层的酒吧大厅、舞池、走道、机房和敞开办公室，1层的宴会厅，2层的休息大厅。其余房间均采用自然排烟。
7 风管与风口布置
风管全部沿梁布置，全空气系统气流组织采用上送上回的形式。风口对气流组织有着关键影响，根据送回风量选择合适的风口，均匀分配，同时避免柱和梁的阻挡，最大可能的减少风量扰动对气流产生的负面效应，才能产生良好的气流组织效果。在本次设计中遵循平均布置的方法，使空调区域可以均匀送风。
Design General Information
1 The source of the design
Hotel is a staff of public places, temperature, humidity, cleanliness, and fresh air volume, etc., had a great influence on guests and hotel staff, etc. Dirty dust in the air is easy to spread some diseases. Therefore, the hotel air environment is more and more taken seriously by the commercial sector. Set up has good ventilation air system of the hotel, is popular among the masses. Hotel air conditioning design is different from office building and department store, such as construction, it has a flat architecture space is large, personnel density is big, room type, etc. Therefore, hotel HVAC system design, choice of cold and hot source and the arrangement of send and return air mouth, must fully consider the hotel of the characteristics of reasonable design.
This design content is a five-star hotel in Guangzhou for 1 to 2 and 1 floor underground layer of air conditioning design.
2 The general situation of the engineering
This project is located in Guangzhou city, a total construction area of 23639 m², total height is 21.731 m, multi-storey building; only one layer underground, the height of 4.8 meters, equipped with chess rooms, bars, KTV rooms, staff canteen, office premises, equipment room, kitchen and laundry, etc.; 5.4 meters high, a total of five layers on the ground, the first layer upon layer, layer height 4.5 meters, 3 ~ 5 layers of 3.9 meters high. The first layer for western restaurant and reception hall; For the conference room on the second floor and massage room; 3 ~ 5 layers as the standard rooms and executive suites, and five layer also has a presidential suite.
3 The project of hot and cold source
Because this project is located in Guangzhou, and warm winter area, for winter heating load demand is not high, and from the perspective of economic operation, time running Angle, convenience of management, maximum limit plays the basis of an analysis of the energy efficiency decides choose air-cooled hot and cold water unit. Carrier selected four units of 30 HXC400A, air-cooled screw water chillers and two cases. Both cooling and heating of hot and cold water unit, air cooled unit and eliminating the boiler room, cooling tower, cooling water pump and cooling room, saving construction investment and the additional equipment investment.
4 Air condition systems
When a larger room space, personnel is more, usually don't have to go to partition the regional temperature control, so appropriate USES air conditioning system. And some of the time different and the room space is small, make adjust different density is not high temperature and the area should adopt fan-coil unit plus independent outdoor air system.
This design for the five-star hotel in Guangzhou 1 to 2 and 1 floor underground layer of air conditioning design, both the hotel lobby, bar, restaurant and other large space, there are chess room, office, lunch rooms, such as the small room space. Choose a large space room return air constant single duct air system. The rest of the board room, KTV rooms, office, etc. The smaller room, room area is small and use time sync, adopting fan coil plus independent outdoor air system. This design is mainly design all air system, fan coil unit plus fresh air system layout, only do not do a detailed calculation.
